The ATC SCM40A floor Standing Speakers are a full range 3-way Floor Standing ATC design. Using world renowned ATC 75mm midrange driver unit, the ATM SCM 40A's ability to reproduce music at realistic levels is truly amazing. The ATC SCM40A floor Standing Speakers employ the same 'soft dome' technology found in the reference systems built for the recording industry. This design feature among others contribute to the wide bandwidth and exceptional dynamic range of this outstanding loudspeaker. Available in real wood veneers and 'professional black' finish, the ATM SCM40A offers all the unique sonic advantages for which ATC speakers are valued the world over.
Manufactured in house to exacting tolerances, ATC's drivers are legendary for their many design innovations. The hand-wound short voice coils use only high density edge-wound flat OFC wire and operate in a precision long magnetic gap. Front and rear magnetic venting not only reduces airflow and noise, but increases power handling and long term reliability. Meanwhile, massive motor assemblies offer no-compromise optimization for each voice coil diameter.
